    摘要: A waterfowl decoy system used by one or more hunters for simulating large numbers of geese and ducks in a field or on a water surface. The system includes a plurality of decoy pennants attached to a decoy line. A plurality of decoy lines joined in series form a decoy line train. Opposite ends of each decoy line include a snap swivel for preventing the pennants and decoy line from becoming tangled. A portion of the decoy line is attached to a top of a line pole for suspending the decoy pennants above a ground surface or a water surface. Also, a portion of the decoy line can be connected to a decoy line animator for moving the decoy line and pennants from one position to another. The decoy system also includes a backpack or dolly with a vertical hand operated vertical spool for holding the pennants and decoy lines thereon and transporting the decoy system to and from the hunting area.

    摘要: A method for automatically calibrating a controller for a valve controlled system follows consistent procedures to make precise adjustments to valve characteristics. The controller is placed in a calibration mode, then the valve settings are modified over a full range of operation. At predetermined levels of operation, the valve settings are maintained at preset values while system performance is measured. After the full range of valve operation has been covered, adjustments are made to the correspondence between the valve settings and the levels of operation in dependence upon the differences between the measured system performance and the predetermined levels of operation. This procedure is repeated to provide average values and also to make changes to valve characteristic curves corresponding to different modes of operation such as single valve and sequential valve modes. Other control parameters may be adjusted by evaluating system performance during normal operation.
